NEW YORK,' N. Y A. CORPORATION OF NEW YORK METAL 'wnmow Appllcation'flled April 18, 1931. Serial No. 531,178.

This invention relates to metal windows of the general type of that shown in Letters Patent of the United States No. 1,692,982, dated November 27, 1928. One object of the invention is to improve the construction of such windows so as to prevent the driving of air inward between the bottom member of the lower sash and the sill and to prevent the possibility of water being driven in with such air. Another object is to improve the construction of the meeting rails of the two sashes, upper and lower, also as to prevent the driving of air between them. Still another object is to provide improved means for securing the glass in place in metal window sashes, so as to facilitate the installation thereof.

The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated, and in which:

Figure 1 is a view in vertical, sectional elevation, partly broken out to save space, showing a metal window, with upper and lower sashes, equipped with the present improvements and installed in a metal frame.

Figure 2 is a detail view on a larger scale showing particularly the construction of the meeting rails.

The sill a, the window frame, comprising also the jambsb, and the head 0, may be formed in any usual or suitable manner, being shown herein as formed of sheet metal, as in The jambs b are adapted to receive the upper sash (Z and the lower sash e and to permit them to slide vertically. The sill a is arranged to cooperate with the bottom member 6 of the lower sash e, and for that purpose is provided, in the construction shown, with a vertical portion a a contact surface a a downwardly extended underclu/t portion a, a contact surface a, and an ndercut portion or wash a The contact surfaces a and a are inclined downward and outwardly and the portion a is inclined inward somewhat so as to form at a a contact line.

of spaced flanges extended downward. In the construction shown the bottom rail is formed integrally, on the inner side, with a flange e and on the outer side with a flan e e, while a third flange 6, intermediate 0 the other two, is secured by a bolt and slot connection, shown at 6 to the underside of the portion (2 of the bottom rail, the slotted connection being provided for the purpose of permitting this flange e to be adjusted in position between the two flanges e .and e. In the construction shown the flange e is vertical and bears at its lower edge directly against the contact surface a* of the sill.

It will be seen that when the lower sash is down a contact between the sash and the sill and the flange e of the sash, a line contact is formed between the angle a of the sill and a the flange e or e of the sash, a contact is formed between the flange e or e" of the sash and the contact surface a of the sill, and a contact is formed between the flange e of the sash and the contact surface a of the sill at its outer edge, so that water cannot accumulate on the contact surface so as to be driven in by wind. The space or spaces between the flanges, contact of which with the sill is thus established, form a dead air space or spaces which can be filled with any suitable material if desired, and inward movement of air from the outside is checked. The several flanges of the sash, in the construction shown, as will be observed, are extended downward from thebot-tom rail progressively further toward the outside for cooperation with the contact surfaces of the sill as described. It will be understood that the inside portion of the sill, inward from the sash, and the outside portion of the sill, outward from the wash (1 may be formed in any suitable manner, as ma be required by the structure to which the window is applied.

The meeting rails of the two sashes are likewise formed so as to afford several contacts with each other and dead air spaces, for the purpose of effectively preventing the driving in of air between the meeting rails. As shown in Figures 1 and 6, the upper member or meeting rail f of the lower sash has one edge portion turned outward, as at f, and is then turned inward obliquely, as at f, while the lower member or meeting rail g of the up or sash d has one edge portion turned inwar as at 9 and then turned upward obliquely, as at g". The other edge portion of the meetin rail f is carried outward beyond the portion f and is then turned downward vertically between the meeting rail of the upper sash and the portions 7, f of the meeting rail 7 of the lower sash, while the other edge portion g of the meeting rail of the upper sash is carried inward beyond the portions 9 and g and is turned u ward vertically between the meeting rail 0 the lower sash and the portion i thereof. In this manner, a broad surface contact is afiorded between the portions f and g of the lower and upper sashes, respectively, a line contact is assured between the edge of the portion f of the lower sash and the portion 9' of the upper sash, a line contact is assured between the edge of the portion 9 of the meeting rail of the upper sash and the portion 7 of the lower sash and line contacts are assured between the edges of the portions f and g on the one hand, and the portions g and f on the other hand, respectively. Dead air chambers are also formed, as at f and g, respectively. In this manner the driving in of air between the meeting rails is effectively prevented.

It will be understood that various changes in details of construction and arrangement can be made to suit different conditions of use and that except as pointed out in the accompanyin claims the invention is not restricted to t e particular construction shown and described herein.

I claim as my invention:

1. In a metal window, the combination of an upper sash of sheet metal having one edge portion of its meeting rail member turned inward at the bottom and then turned upward obliquely and having the other free edge portion carried inward beyond the first named portion and then turned upward, and a lower sash of sheet metal having one edge portion of its meeting rail member turned outward at the top and then turned downward obliquely and having the other free edge portion carried outward beyond the first named portion and then turned downward.

2. In a metal window, the combination of an upper sash of sheet metal having one edge portion of its meeting rail member turned inward at the bottom and then turned upward obliquely and having the other free edge portion carried inward beyond the first name portion and then turned upward, and a lower sash of sheet metal having one edge portion of its meeting rail member turned outward at the top and then turned downward obliquely and having the other free .ward obliquely and havin the oblique portions of the two rail portions being formed for contact between the vertical portions.

3. In a metal window, the combination of an upper sash of sheet metal having one edge ortlon of its meeting rail member turned mward at the bottom and then turned upedge portion carried inwar beyond the first named portion and then turned upward, and a lower sash of sheet metal having one edge portion of its meeting rail member turned outward at the top and then turned downward obliquely and having the other free edge portion carried outward beyond the first named portion and then turned downward, the oblique portion of each rail having its extreme edge arranged for contact with thel side of the vertical portion of the other ra1 4. In a metal window, the combination of an upper sash of sheet metal having one edge portion of its meeting rail member turned inward at the bottom and then turned upward obliquely and having the other free edge portion carried inward beyond the first named portion and then turned upward, and a lower sash of sheet metal having one edge portion of its meeting rail member turned outward at the top and then turned downward obliquely and having the other free edge portion carried outward beyond the first named portion and then turned downward, the vertical portion of each rail having its extreme edge arranged for contact with the member of the other rail.
